Abstract

A method to cut a bar of double or triple section interconnected in a continuous nodule, in the production at high speed of elongated metal bars from billets, which when producing a double section bar comprises the phase of passing the bar through the opposite laminators of at least one rolling box in order to reduce the cross-sectional area of each section, the active compressive force of the laminators being applied asymmetrically on each section, said force being applied with greater intensity together with the interconnection nodule whereby the longitudinal elongation of each section adjacent to the nodule is greater than the elongation of the same section opposite the nodule, creating lateral traction forces in the nodule that cause the sections to separate progressively from each other.
